Application filed J'anuary 24 1320. Serial No. 353,808.

This invention relates to hub constructions for demountable wheels,pertaining more particularly to constructions adapted for use inconnection with wire wheels.

The present invention is designed to 'meet general conditions by the useof a hub construction which is simple and efficient in operation,durable in construction and which can be manufactured at a relativelylow cost. In addition, the construction is such as to provide for theuse of practically two elements one of which remains permanentlypositioned 'asthe inner hub member,' the other being demountable asaunit, these two the inventionis hereinafter disclosed, said inventionconsists in the improved'construc tion and combinatlon of parts, as morefully described hereinafter, illustrated 1n the accompanying drawings,and more particularly pointed out 111 the appended claims.

latter being indicated at a, and carrying one of the elements of arollerbearing structure, indicated generally at -b-. 'c indicates amembermounted on the axle a and driven thereby, saidelement'0 beingadapted to havea splined engagement with the inner hub-member 10, thelatter having splines arranged. on its interior in complemental,relation-to splines carried by member 0. The hub member :10 carries aninternal flange 10 which, in connection with, the outer member ,of thebearing 'bf serves as a part of the general structure for retan nng theinner hub member 10 in its posltion on the aXle housing a "Thisparticular construction is more or less illustratlve, 1t belngreadllyunderstood that varlous Ways of supportlng an n ner hub memherpermanently and rotatably on an axle housing and operatively connectingthe hub member-with the drive shaft, or axle, may

be employed, it being'understood, of course,

that the inner hub member remains as a permanent part of'the completedassembly,

and that the particular'method of driving" I this hubjmember may begreatly varied.

So far as the present invention is con cerned, the particular "portionsof the inner hub member 10 entering into the specific form'of theinvention are the rear; annular seat '11. thefouter endformation,-and'the spline formation which cooperates with the outer hub member 12.As shown inFig. 1, the seat '11 is'located adjacent the inner end of theouter hub member, the latter havinga complemental'face, 12 which seatson the seat .11 whenthe hubs are assembled. 'The. I

seat 1 1 is preferably more orless conical and of sultable lengthaxially, while face 12 is of complemental formation with. an axiallength in excess vofjt-hat of seat 11. Inpractice, the seat 11 islocatedwithin the zone defined by the planes at-the opposite sides, of

stood that thesets, of spokes'indicated at -'eand are to beIconsid-eredprac tically as spokes primarily designed. for re} the rim (not shown),so that. itactsfasithe support for radial. stresses, it being undervdial load 00116 17610113, This particular' ar-n sections 14? beingfreely insertable within these spaces, and angular movement of the capserves to cause the threaded portions 13 and let to become engaged andthus draw the cap inwardly. As presently pointed out, this inwardmovement of the cap acts to bring the face 12 into frictional engagementwith seat 11 and serves to bind the two hub members firmly together,this being obtained, by the angular movement of the cap suflicient toproperly engage the threaded portions.

To retain't-he cap in such position, a suitable locking structure isemployed. the particulareinbodimentshown being that of an annularresilientinember 15 having laterally extending spring fingers '15 whichare adapted to engageinto recesses 10" of the hub member, the device 15,in this case, be- .ing secured to the cap as by rivets or otherwise.Element 15 may be of single thickness but is preferably of a multiplethickness or laminated, and the position of the elements relative to thecap is such that after the cap has been entered and moved angularly toengage the threads, the lingers 15'? will be inovedinto position withinrecess 10 ,'so that these fingers will act to normally retain the partsin such position.

The fingers and the configuration of the re- 'cesses 1O are such thatunder ordinary service conditions, the cap will be prevented from avretrograde 'iiiovement sufficient to affect the clamping action producedby the threading of the cap to position. When-it is 'desired to releasethe parts, a suitable wrench is applied to the end of the cap and byapplying considerable pressure angularly exerted the cap may ber-otatedin the reverse directiomthe pressure serving to disengage the fingers 15from recesses 10", after which the continued rotation of the cap so asto bring its threaded portionsv lt into the reently described. b

As shown in the drawings, the cap is processes between the section 13will permit the removal of the cap; and of the wheel as presvided withan annular conical seat 14 with Y which a fa'ce of'the outer hub membercon-V tacts, caplet having aconfiguration as will produce a recess intowhich this'outer end of the. outerl hub member will extend, as showninlEigs. land 5; "This result'canbe pro due-ed indifferent ways, as for'instance by spinning down .;over the hub portion the outer edge portionof the cap,- thus locating proximity to the'seat 1 1 the outer edgeofthe hubportion within an outwardly inclined recess which will serve toprevent detachament of the cap from the.

hub member and serves to move the hub member in the direction of ts axisthr-ougl the threading movements of the cap.

, It will be understood, of course, that this particular connection ofhub member and cap is not such as to produce a fixed engagement such aswill prevent relative rota- "illVe movement between these parts, itbeing essential, in the particular embodiment shown that such relativerotative movement of the cap be permitted. However, the seat 14* servesto move the hub member to its assembled position by the threadingaction, and the outer turned over edge of the cap,

indicated at 14 will serve to withdraw the hub member 12 from the tightfrictional engagement w th the hub member whenthe cap is unthreaded andthen drawn out.-

wardly.

. The outer hub member preferably carries aportion 12 which is slightlyconical, with the large" end towards the rear of the hub, this portioncarrying splines 12 which cooperate with splines 10 of the'inner hubmember, this conical shaped portion 12 cooperating with thecompleinental outer of the splines 10 in producing a frictionalengagement therebetween, when the parts are assembled, so that not onlydo the splines 12 and 10 operate in providing for the drive action,butthis frictionalengagement also provides an additional assurance thatthe two hub members will rotate in unison.- Obviousl this arrangementWill also )e'r'init of ready tightening and. loosening of the outer hubmember from the splines 10 by the unthreadingmovement,ofthe cap. 7

As will be seen, the outer hub ineiri'ber has aset of spokes whichextend to a point in From the above, it will be readily-understood thatthe outer end of hub member 12is properly seated through the fact thatthe cap is itself firmly and positively. locked to the inner hub memberthus assuring the maintenance of the outer hub relative to the axis ofthe hub, it being understood that the seat 11 located at the oppositeend of the hub member performs 'a similar duty the opposite'hub end, sothat both ends of the hub are positively seated in a manner to maintainthe true'running position of the hubs when the parts are. assembled. Inad dition,flthe faces 10 also serve as supports for the outerhub member.

From the above it will'beseen that there are no parts of thedem'ountabl-estructure which are. separable, the cap being firmlyattached to the outer hub member and meniber 15 securedto the-cap, sothat thereis no liability of any parts becoming lost or dis-v placed bythe assembling or taking' down of memes employ the wrench to rotate thecap itself in the opposite direction, the unthreadmg mpvementdisengaging the frictional engagement provided by the seat 11 and thefaces 10 leaving the demountable portion free'to be easily lifted offwhenthe cap has been rotated the proper distance.

As will be clear, the construction is simple and efiicient in operation,the-relative arrangement of parts being such as to insure a firm supportof the outer hub member when in its assembled position and capabletowithstand the stresses and strains which are placed in the wheel whenin use. Owing to the location of the various seats ZIHC supports betweenthe members, it willbe readily understood that the outer hub member neednot be of massive formation or of excessive- 1y thick material so thatit is'capable of be ing die pressed and thus-provide for a low cost ofmanufacture and at the same time produce the' desired strengt-h ofstructure. Obviously, the construction is such as to provide fordurability and long service condi-. tions, since the parts are'soarranged as to equalize strains and maintain the integrity of thestructure. The formations are such as to permit ready production and thecost of manufacture will be relatively small.

lVhile I have herein shown and described a preferred embodiment of theinvention, it will be readily understood that variations and changestherein may be found desirable .or essential in meeting the variousexigene cies of use, and I desire to'be understood as reserving theright to make any and all. such changes and modifications as may befound desirable or necessary, so far as the same may fall within thespir t and scope of the permanent drive engagement with a drive.
